With each new invoice, you create an invoice number will be assigned to it and those invoice numbers will increase sequentially. At any time, you can customize the format and numbers used

Setting up your own invoice numbering system can help you organize your business. You can customize your invoice number and use a combination of numbers, letters, and symbols. If your invoice numbering system does not end in a number (e.g. “AA”), Invoice2go will automatically assign a number to it (e.g. “AA1”, “AA2”).

Invoice2go allows you to create invoices out of order in reference to your number system sequence if you ever notice a gap in your invoice numbering (e.g. “AA1”, “AA3”) which could be caused by an invoice not fully syncing online due to poor internet connection or weak mobile signal or because it was manually deleted.

Any changes will only apply to future invoices.
